  • Phenol and cyclohexanone manufacture
    Patent number: 3959381
    Abstract: Method of producing phenol and cyclohexanone in enhanced yields consisting essentially of contacting cyclohexylbenzene, preferably in the presence of a member selected from the group consisting of cumene and cumene hydroperoxide, with an oxygen containing gas to form 1-phenylcyclohexyl hydroperoxide containing intermediate product, optionally purifying said intermediate, contacting the 1-phenylcyclohexyl hydroperoxide intermediate product with an acid cleavage catalyst in the presence of an alkanone of from 3 to 6 carbons and recovering the formed phenol and cyclohexanone.
    Type: Grant
    Filed: October 22, 1970
    Date of Patent: May 25, 1976
    Assignee: Texaco Inc.
    Inventors: Alfred Arkell, Peter A. Riedl, Edwin R. Kerr
  • Hydroalkylation catalyst and process
    Patent number: 3957687
    Abstract: Catalytic activity of a catalyst composition containing a Group VIII metal on an acidic oxide support consisting essentially of a silica alumina cracking catalyst may be increased by the process which comprisesCalcining said catalyst composition at 1350.degree.-1450.degree.F for at least about 2 hours thereby forming a calcined catalyst composition; andReducing said calcined catalyst composition at temperature of above about 850.degree.F. for at least about 8 hours thereby forming a catalyst composition characterized by increased activity.
